Subhashini, V., & Swamy, A. (2018). Phytoremediation of Pb and Ni Contaminated Soils Using Catharanthus roseus (L.). Department of Environmental Sciences, ANU, Guntur (AP), INDIA.
This study focused on the phytoremediation of lead (Pb) and nickel (Ni) contaminated soils using Catharanthus roseus (also known as the Madagascar periwinkle) as the chosen plant species. The research was conducted at the Department of Environmental Sciences at Acharya Nagarjuna University in Guntur, Andhra Pradesh, India.
Phytoremediation is a sustainable and eco-friendly approach to remediate contaminated soils using plants to extract, detoxify, and accumulate heavy metals from the soil. Catharanthus roseus is known for its ability to tolerate heavy metals and has been used in previous studies for phytoremediation purposes.
The researchers conducted experiments to determine the efficacy of Catharanthus roseus in removing Pb and Ni from contaminated soils. They analyzed the levels of heavy metals in the soil and the plant tissues before and after the phytoremediation process.
The results of the study showed that Catharanthus roseus was effective in accumulating Pb and Ni from the contaminated soils. The plant showed a significant reduction in the concentrations of these heavy metals in the soil, indicating its potential for phytoremediation purposes.
Overall, the study demonstrated the potential of Catharanthus roseus as a promising plant species for the phytoremediation of Pb and Ni contaminated soils. Further research is needed to optimize phytoremediation strategies using this plant and to explore its potential for other heavy metal contaminants.
